Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is described in further detail:
As shown in Figure 1, 2, 3, a kind of hydraulic sensing device with simple exhaust structure, including adapter 7 and hydraulic conversion signal output element 6 with for controlling the rotating switch 2 of aerofluxus, face of cylinder inner chamber body 9 is set in adapter, cavity is communicated to the sensing position of hydraulic conversion signal output element, the lower end of adapter is the threaded post 1 for connecting automobile brake wheel cylinder air vent to be measured, and the end connecting post has the air inlet/oil-in 8 being communicated in inner chamber body；The upper end of adapter has aerofluxus/oil export 4, and aerofluxus/oil export 4 external cleaning sebific duct is to reclaim brake fluid.Check valve 5 it is provided with between the outlet at aerofluxus/oil export 4 and cavity 9, check valve 5 is made up of cone spool, spring and surge chamber, surge chamber connection aerofluxus/oil export and cavity, spring suppression is in the bottom surface of buffering locular wall with cone spool, and valve element circle cone match is on the face of cylinder of cavity outlet.Rotating switch 2 is positioned close to the position of cavity outlet, and rotating switch is laterally passed in and out in cavity by a rotation bar, to realize connection and the blocking-up of aerofluxus/oil export and cavity；Turning end at rotating switch is stretched out a rear flank of adapter and is connected a handle 3, facilitates rotating switch.Hydraulic conversion signal output element is positioned at the opposite side of adapter, and the signal output interface of hydraulic conversion signal output element can dock with various holding wires, it is simple to outer signal processing means is reliably connected, and makes the transmission of signal high-fidelity.
When not touching on the brake, cavity outlet does not has gas/oil discharge, and the cone spool of check valve is under the action of the spring, taper seat coordinates with the cavity outlet face of cylinder, goes into linear sealing, it is achieved the unidirectional outflow of brake fluid, brake fluid can be stoped to reflux, it is to avoid the suck-back of air, there is good air-tightness.
The workflow of above-described embodiment is as follows: 1. backs out the bleeder screw on vehicle wheel cylinder, and is screwed on by threaded for this utility model device post；2. aerofluxus/oil export connects oil drain hose, and the flexible pipe other end is placed on oil storage in cleaning container；3. closing rotating switch, brake pedal for several times, is then fixed on extreme lower position by continuous brake pedal；4. open rotating switch, make the gas in wheel cylinder discharge；5., after discharging gas, rotating switch is closed；6. step is repeated 3., 4., 5., until the brake fluid not bubbles discharged from flexible pipe；7. from the signal output interface read voltage value of hydraulic conversion signal output element；8. loosen the brake, take off the flexible pipe on aerofluxus/oil export, check that the brake fluid in fluid reservoir is the most enough；9. back out this utility model device, and original for vehicle bleeder screw is screwed on.The most respectively other each hydraulic wheel cylinder are carried out stress test.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
